Application filed November 1911, Serial No. 661,?65.

To all whom 7'5 may (inure/vi lie it known that l, Herman 'lronnnun, acitizen of the United Sta residing in the borough oi Bronx, city county,and State ot New York, have invented a new and llsljiill Improvement inPlate-'I'Iolding Means for 'lrinting-Machines, of which the following isa description.

This invention relates to clamps r holders for stereotype and othersimilar plates, and has particular reference to means by which plates ofthe character noted can be properly lined up nnd securely clamped on theplate" block.

Among the objects of my invention may be noted the following: to providea clamp or holder of-the character stated which can be quickly set inplace and clamped in pos'-; tion. against the margin of the. plate so asto lmldthe'letter firmly and in proper alinement; to provide n pl ateholding clam p with means by which it can be made to clean the track inwhich it. operates; to provide a plate holding clamp with means forlimiting the movement of the base thereof in two directions so that theclamp may be readily removed from the block when the base has reachedthe proper position, and so that the operative position of the clamp inthe block maybe instantly secured; to provide a plateclamp or holderwith means whereby it may engage the periphery and bottom oi? the plateso as to obtain upon the latter a firm clamping grip and also be heldfirmly in the block against displncement; to provide it clamp forholding plates, which can be titted from the block immediately upon itsrelease from the plate and without the necessity of having to slide thesame along the groove ol the block until the open end thereoi isreached: to provide a structure of block in combination with o clampwhereby the latter is firmly held in position against displace-- ment;to provide a block of a fornii to a il'ord a support for the plate atand near the one 11ers thereof; to provide a plate-clamp with means forcoiiperotion with a plate-shifter; to provide a plate-holder with meansfor supporting the corners of the plate; and to provide certain detailsof construction by which the foregoing objects are secured and whichmake of the clamp a cheap, simple and effective instrument for thepurpose.

With tlu-robove objects in view, and others which will be detailedduring the course of part l'eatlurs, elements and combinations ol'elemenls oil as hereafter described nnd clzieiluell.

in order that my invention may be clearly understood, 1 have provideddrawings u herein:

llpon reference to the drawings, .liigs-tl to 8, it will be seen limi myclump or holder consists oi? two principal parts, viz. a base-piece anda holding screw. The hose-piece l is oblong in form and has a screwthreaded aperture .2, tornu-d. therein, and also has, as a partthin-(wt, a verlicnlly-cxlending pin ti, near one end and at onelongitudinal margin liner-col". The lopplccc -i may be slightly l uejrrthan the base-piece end is rectangular intorm, but particularly has itslongitudinal edges beveled, as at 5, so as to converge from top tobottom. ,l 'lilber one or both of the edges may be beveled. The, degreeof the angle or bevel oi the sides is important only in its aspect ofcorrespoiuling approxi merely with the bevel of theporiphory or edges,ot'the plate. ()n the bottom of the top-piece is preferably rigidlysecured a log (3, made substantially in the form of o square, with twoopposite angles slabbed oil slightly and leaving oppositely-extcndinglips 'i projccti-ng a slight distance beyond the bases ot' lhc beveledsides of the toppiece.

., noreqme used, a great strain is brought upon the plate and clamps,and the tight grip be tween the clamps and block prevents the clampsfrom shitting while the plate is be iug moved to the desired register.

In the form oil. Fig. 9, the lug 6 ismade independent of the top-pieceand the latter. is provided with a countersink 522,-in the bot tomsurface, while the lug is provided with a vertical pu'ojoction Q23,torcoopcration with said countersink. Thus, the clamp is formed in :lourparts instead of in thrco. By this construction, the top-piece, when inthe block, may swivel upon the lug (3 and be made to. assume any anglenecessary for it to properly coiiperate with the plate, regardless ofthe 'EOKITL'OE the latter or its position on thewbloclt.

In the form of Fig. 1.0, a long bar 24 takes the place of the toppicce,the bottom surface of which has applied thereto a plurality oflugs ii,the other complcincntal clamping parts being the some as in the otherforms of my invention.

It frecnuzntly,happens thatone or more of the corners ofthc plate willextcndovcr the edge of a flange i l of the. ordinary block and hangabove a groove in said hloclr without any support. This, nccessitalrsthe provision of independent means in the groove for supporting saidcorners to prevent them "from becoming bent or otherwise injured. Invery great measure, this objection and fault is remedied by" thestructure of my block, vim, by providing the overhanging flanges 14,which reduce the size of the top of the slots in the block and afl'ord avery material -iupport for the corners of the plate. However, to avoidany possibility of bending, or breaking the corners of the plates, underthe conditions noted, I may make the lu (3 sufficiently extensive toproject bcyonr the top-piece and well into the groove of the block so ato provide" a? corner support tor the plate. as shown at 526, inIiig. 1. This is a very otlcctivc means for the purpose, since tho lugwedges tightly in the slot bctwccn the ()PIH'ISKtl beveled edges '18 ot'the flanges and has its top surface lying flush with the top surfaces ofsaid flanges.

1n the drawings, I have shown only a flat plalc and flatsupportlug-block; but, I desire it understood that my invention isequally applicable to curved or cylindrical blocks and that the clampsare just as efiectivc on any form of surface to which a printing-platecan be ac lapted.

Having thus dcscribcdmy invention, What. 'li claim and desire to secureby Letters Patent is pieces 1n cooperative relation, the base-piecehaving a pin on its lop sin-taco for limit- Imgg the movement of saidpiece in opposite directions.
